Deputy Director Yang... Chen Geng only knew that Deputy Director Yang's surname was Yang. As for the specific name? Sorry, that was a secret... The arrival speed was faster than he imagined. When Comrade Liu and Comrade Feng told him that Deputy Director Yang was coming soon, he thought it would take two or three days, but that night, Deputy Director Yang stood in front of Chen Geng. The speed was so fast that Chen Geng was amazed. He couldn't help but ask: "Chief, didn't you ask the civil aviation company to arrange a temporary flight for you?"

Deputy Director Yang: "That's not the case, but the Air Force has a night flight training, so I asked them to arrange a two-seater fighter to take me for a while."

Chen Geng: "..."

I have a saying that MMP is not known to be said or not?!

What is luxury? This is luxury. When you want to fly, you can arrange a fighter plane to fly over. What a crazy thing?!

Looking at the Deputy Director Yang, who had been sitting in the fighter plane for several hours, there was no sign of fatigue on his face. Chen Geng couldn't help but swear in his heart: This physical fitness is a beast!

"Comrade Chen Geng, I'm sorry for today's request." Although Deputy Director Yang is a general, he adhered to the military's pleasure and apologized to Chen Geng first: "Please understand, I'm not going to do anything, but this technology is too important to the safety of the leaders. I need to see it myself and negotiate with you about this technology issue."

Hearing this, Chen Geng felt much better, and his previous depression was much less. He nodded and said, "Okay, but I still retain my previous attitude: it is impossible for the Guard Bureau to seal this technology, and I am not afraid to tell you the truth. Toyota in Japan is also developing similar hybrid drive technology. Our technology is to compete with them."

"There is something like this?" Deputy Director Yang couldn't help frowning: If Japan's automobile manufacturers are also developing similar hybrid drive systems, then this matter really needs to be carefully considered and there is no point in blockade.

"As long as you really want to verify, it shouldn't be difficult, right?" Chen Geng asked.

Too!

Deputy Director Yang agrees with Chen Geng's words. This matter must be verified. If Toyota is really developing a hybrid drive technology similar to Runhua Industrial's hybrid system, it will definitely be bad. Chen Geng really has no reason to lie about such things that can be bad by checking.

Seeing that Deputy Director Yang's face relaxed, Chen Geng felt relieved. To be honest, he was really worried that Deputy Director Yang would directly use military control to force the sealing of this technology after he thought that this technology was extremely important for protecting the chief. If he really did this, Runhua Industrial would lose a lot, but fortunately, it seems that he did not plan to do this now, which is a good thing.

After rushing over so anxiously, Deputy Director Yang must have been not chatting with Chen Geng. After a brief greeting for two games, he asked anxiously: "Comrade Chen Geng, where is the car? Can you take me to see the car first?"

Chen Geng: "Don't worry about the car. I'll take you to understand the principles of the operation of this power system. After understanding these things, let's understand the car."

Deputy Director Yang thought for a while and finally nodded: "Okay."

Anyway, you must understand the principles of this system, and there is nothing wrong with understanding this first.

………………………………………

Chen Geng had information about this hybrid system in his office. He brought Deputy Director Yang to his office. Chen Geng didn't be polite to him, so he poured a glass of water and placed it next to him. He immediately took out the information that had been prepared in front of him: "I will briefly introduce to you the basic principles of the operation of this hybrid system. The core of this system is this e-cvt transmission. This transmission mechanism can allow the operation of two power input sources of the internal combustion engine and the electric motor at the same time, and it also has the function of power generation... From a structural perspective, is it a bit like the solar system?"

Adhering to the glorious tradition of not being able to name a name and being too lazy to give a new name, Runhua Industrial's hybrid transmission mechanism inherits its original real name: e-cvt gearbox.

Deputy Director Yang looked carefully and found that as Chen Geng said, this set of e-cvt automatic transmission is really like a recuperating western-style gearbox. The gear in the middle is like the sun in the solar system. The four gears in the middle are the planets revolving around the sun in the solar system. As for the outermost ring gear, it is the orbit of Pluto, the outermost outermost outermost solar system.

Pointing to the e-cvt automatic transmission that looks particularly weird and is completely different from all the automatic transmissions nowadays, Deputy Director Yang told Chen Geng: "What is the purpose of this design? What is the effect of achieving it?"

"This is what I want to tell you next," Chen Geng nodded slightly: "The sun gear in the middle connects to the No. 1 motor, converting the heat energy of the internal combustion engine into electrical energy and storing it into the energy storage battery carried by the car itself; the planetary gear set in the middle connects the internal combustion engine, and the outermost ring ring connects the No. 2 motor and the power output shaft. This No. 2 motor is also an all-in-one motor/generator.

Through the coordination and coordination of the electronic control system, this set of e-cvt automatic transmission can realize three major functions: pure electric driving function, pure internal combustion engine form function, and the synergistic function of internal combustion engine and electric motor.

In addition to these three major achievements, there are other auxiliary states, such as generating power while driving. When stepping on the brake, the brake system is not braking, but the No. 2 motor is braking through the reverse drag, that is, the No. 2 motor is generating power at this time; for example, when starting, the motor assists the gasoline engine in acceleration, making the entire starting process lighter..."

Deputy Director Yang nodded repeatedly when he heard this, and only felt his vision wide open. After Chen Geng finished speaking, he couldn't help but exclaim: "What a wonderful idea, a clever craft! I really don't know how you came up with such a clever structure."

"What do you think," Chen Geng said with a wry smile: "We have spent more than 100 million on this system every year over the years, and last year it was more than 200 million. The combined R&D costs are 700 to 800 million."

Seven or eight hundred million, it doesn’t sound much, but this is seven or eight hundred million in the 1980s and 1990s. In the era when an annual sales of more than 30 million in this company is a large enterprise, it takes seven or eight hundred million to develop a power system, which sounds like a numb feeling!

Deputy Director Yang's scalp was numb.

When I heard that Runhua Industrial had spent 700 to 800 million yuan in R&D funds, I was originally planning to do Chen Geng's work and persuaded him to hand over this technology to the country, but I couldn't say this anymore: This is a technology that cost 700 to 800 million yuan to be developed. Do you say that you donate it?

He believed that the reason why Chen Geng dared to spend so much money to study this technology must be that he was highly optimistic about the future market prospects of this technology. He was really betting on the future. If he dared to ask Runhua Industrial to hand over this technology to the country for free, it is estimated that the leaders of the East China Military Region will be able to directly beat themselves to death at home.

Looking at Deputy Director Yang, who was trying hard to control his expression, but the corners of his mouth were twitching gently, Chen Geng laughed in his heart: I just think you are afraid! Pretending to not see it, Chen Geng continued: "Of course, this money has not been spent in vain. As the fourth automatic transmission in the world after At, CVT and DSG, our e-CVT automatic transmission has two significant advantages. The first is that it does not have the transmission commonly used by traditional CVT automatic transmissions. The connection between the moving steel belt, engine, transmission and motor is completely a hard link to the gears, so our e-cvt automatic transmission has a high transmission efficiency, which is not only far higher than the traditional cvt automatic transmission, but also higher than the at automatic transmission. It is equivalent to the dual-clutch transmission used in manual transmission and F1 racing cars, which is equivalent to this e-cvt automatic transmission that combines the comfort of the automatic transmission and the high efficiency of the manual transmission.

As for the second point, it is something that all automatic transmissions, especially the CVT automatic transmission, cannot do. Even because there is no limit on the transmission steel belt, the e-cvt automatic transmission has a high torque, which can reach 450 Nm. If it is a bulletproof sedan and is manufactured with aerospace technology, we can completely create a gearbox that can withstand torque of more than 2500 Nm... But these are actually not the most difficult things."

Deputy Director Yang was indeed deceived. He heard Chen Geng say this, and he couldn't help but be surprised: "Isn't this the most difficult?"

"Of course it is not the most difficult. The most difficult part lies in the design of the control software and the calibration of various data," Chen Geng said: "You have also seen that our e-cvt automatic transmission not only has physical gear like a traditional manual and at automatic transmission, but also wants to coordinate the work of two motors and internal combustion engines and clutches at the same time. Therefore, it puts forward very high requirements for electronic control systems and control software, control rate and system calibration. Not only is the control software much more complex than ordinary cvt continuously variable transmissions... In fact, the control logic of ordinary cvt transmissions is almost the simplest among all automatic transmissions... and it requires a lot of experiments and a large amount of data accumulation. Do you know how much we spend on this electronic control system alone?"

Before Deputy Director Yang could speak, Chen Geng raised his finger first: "70%! 70% of the entire development cost is invested in the development of control software."

"..." Deputy Director Yang had no idea what to say. He just wanted to curse: 70% of 700 million to develop a software?! It was crazy! But...

wrong!

Deputy Director Yang suddenly realized a problem and asked weakly: "This... Since this system is so complicated, in terms of reliability..."
